Constructs used to produce AAV included pGP-AAV-syn-GCaMP-WPRE and the Cre recombinase-activated construct pGP-AAV-syn-flex-GCaMP-WPRE. Virus was injected slowly (30 nL in 5 minutes) at a depth of 250 μm into the primary visual cortex (two sites, 2.5 and 2.9 mm lateral from the lambda suture). For population imaging and electrophysiology (Fig 2-3), AAV2/1-syn-GCaMP-WPRE virus (titer: ∼1011 (link) -1012 (link) genomes/mL) was injected into the visual cortex of C57BL/6J mice (1.5-2 months old)6 (link). For dendritic imaging (Fig 4, 5 and 6a-f), sparse labeling was achieved by injecting a mixture of diluted AAV2/1-syn-Cre particles (titer: ∼1012 (link) genomes/mL, diluted 8000-20,000 fold in PBS) and high titer, Cre-dependent GCaMP6s virus (∼8×1011 (link) genomes/mL). This produces strong GCaMP6 expression in a small subset of neurons (∼3-5 cells in a 250 μm × 250 μm × 250 μm volume), defined by Cre expression56 (link). Both pyramidal (Fig. 4-5) and GABAergic (Fig. 6) neurons were labeled using this approach, but they could be distinguished based on the presence or absence of dendritic spines. Post hoc immunolabeling further identified the imaged cells. For specific labeling of parvalbumin interneurons (Fig. 6g and Supplementary Fig. 12), Cre-dependent GCaMP6s AAV was injected into the visual cortex of PV-IRES-Cre mice57 (link). Individual somata (Supplementary Fig. 12) and dendritic segments could be recognized (Fig. 6 g, h, total length of imaged dendrite: 2.86 mm), but the high labeling density made it difficult to track individual dendrites over long distances.

Brainstem and spinal cord of aged symptomatic M83 mice were dissected from brains previously stored at −80°C. Tissue was sonicated in sterile PBS (100 mg per 1 ml of buffer) with a handheld probe (QSonica). Homogenates were cleared by centrifugation for 5 min (3,000 g, 4°C) and the resultant supernatant (lysate) was recovered and stored at −80°C until injection. Purification of recombinant α-Syn proteins and in vitro fibril assembly was performed as previously described (Murray et al., 2003 (link); Luk et al., 2009 (link)) using human α-Syn1-120Myc or WT full-length human α-Syn (5 mg/ml). PFFs were collected after 5 d of incubation at 37°C. PFF preparations were diluted into sterile PBS and sonicated briefly before intracerebral injection.

Ser(P)-129 α-syn antibodies and the antibody raised to total alpha synuclein were commercially available and purchased from Abcam (EP1536Y,81a, MJF-R13), Wako USA (pSyn#64), and BD Bioscience (Syn1). Vendors report that the Ser(P)-129 α-syn monoclonal antibodies were raised against synthetic human α-synuclein peptide spanning 124–134 region with a phosphorylated Ser 129 residue. This peptide sequence was originally constructed by Fujiwara et al, and used in their seminal work that led to the discovery of extensive α-syn phosphorylation at Ser 129 reside in Lewy bodies (Fujiwara et al., 2002 (link)). Monoclonal antibodies developed against synthetic α-syn aa 124–134 (phospho 129) peptide were validated using other antibodies that label Lewy bodies in post-mortem brain sections (Baba et al., 1998 (link); Fujiwara et al., 2002 (link)).
Clone EP1536Y is a monoclonal IgG antibody raised in rabbit and may be suitable for use in immunoblotting and immunohistochemistry (Perez-Revuelta et al., 2014 (link); Prusiner et al., 2015 (link); Tuttle et al., 2016 (link); Arawaka et al., 2017 (link)). Clone 81a is mouse IgG2a also used in immunoblot and immunohistochemistry applications (Tuttle et al., 2016 (link); Dieriks et al., 2017 (link)). MJF-R13 is a rabbit IgG monoclonal antibody used in immunoblotting experiments (Brahmachari et al., 2016 (link)). Clone pSyn#64 is mouse IgG1 suitable for immunoblotting and immunohistochemistry (Jiang et al., 2016 (link)). Clone Syn1 is mouse IgG1 raised to rat α-syn peptide aa 15–123, has not been further mapped within that peptide, but has been previously evaluated for specificity (Perrin et al., 2003 (link)). For additional primary antibody information and secondary antibody information see Table 1. Optimal secondary concentration was determined by serial dilution starting with the vendor recommendations. pS129-α-syn antibody concentration was confirmed using a BCA Protein Assay Kit (Pierce) with a γ-globulin protein standard, and all antibodies diluted to working stock concentrations of 0.1 mg mL−1.

For cellular experiments, α-syn proteins were assembled into filaments by incubation at 37°C at concentrations greater than 5 mg/ml in sterile phosphate buffered saline (PBS, Invitrogen) with continuous shaking at 1050 rpm (Thermomixer R, Eppendorf, Westbury, NY). Experimentation was planned so that α-syn would be visibly assembled (by filamentous clusters observed in the solution) by the day of cellular experimentation. α-Syn fibrils were diluted to a concentration of 1 mg/ml in sterile PBS and treated by water bath sonication for a minimum of 2 hours. In experiments where large fibrils were separated from small polymers, diluted fibrillized α-syn (prior to sonication) was centrifuged at 16,000 × g for 5 min, and the supernatant was removed and the pellet was re-suspended in sterile PBS. Protein concentrations of the original diluted fibrils and the supernatant were measured by BCA protein assay (Pierce). Concentration of the large fibrils was determined as the concentrations of [total - supernatant]. All samples were sonicated in a water bath prior to addition to cell culture media. Unless otherwise specified, cells were treated with 1 μM of recombinant 21–140 α-syn fibril mix.

Example 8

Ceftriaxone (at 3 ug/ml or 1500 ug/ml) was mixed with human intestinal chyme alone, or with chyme plus SYN-004 (8 ug/ml) or with chyme plus the beta-lactamase inhibitor sulbactam, (20 mg/ml) or chyme plus both and then the samples were flash frozen. The flash frozen samples were thawed on ice and sulbactam was added to some samples, the protein was precipitated with acetonitrile and the samples were analyzed for ceftriaxone concentration by LC/MS-MS. The table below provides results from triplicate samples.

For immunofluorescence, mice were PBS and 4% PFA-perfused, brains were harvested, post-fixed in PFA, dehydrated in 30% sucrose and embedded in OCT. 14 μm-thick frozen sections were permeabilized and blocked in 0.5% TritonX-100 and 5% Bovine Serum Albumin in 0.5% TritonX-100/1X PBS, respectively. Sections were incubated with primary antibodies in blocking solution overnight at 4 °C followed by incubation with 488, 564 and 647 Alexa-Fluor conjugated secondary antibodies for 1 h at room temperature. After secondary antibody incubations, sections were washed with 0.1% NP-40/1X PBS. DAPI was used to detect cells nuclei. Sections were mounted using ProLong™ Diamond Antifade Mountant (P36961; Life Technologies). The primary antibodies used were: Tyrosine Hydroxylase (TH) (1:1000; ab113, Abcam), hα-SYN (1:300; ab138501, Abcam), TMEM119 (1:500; ab209064, Abcam), CD16/32 (1:100; #101301, BioLegend) and CD3 (1:200; 100347, BioLegend). For staining involving hα-SYN, heat-mediated antigen retrieval was performed using DAKO retrieval solution (S1700; DAKO). All images were acquired with a Nikon Ti-E Eclipse Microscope using a 20× objective (Plan-Apo, 0.75 numerical aperture) or a 60× oil objective (Plan-Apo, 1.4 numerical aperture). Confocal images were acquired using CREST X-Light V2 Spinning Disk. Z-stacks of 60× images were collected at 0.5 μm increments with a total thickness of ~ 6 μm. Images were captured with an ORCA-fusion camera (C14440-20UP, Hamamatsu) or an Andor Zyla camera (Zyla 4.2 sCMOS, Oxford Instruments). Large scan function with Z step focus was used to capture stitched images of the SN using a 20× objective. Confocal images are shown as maximum intensity projection images. Images are representative of the respective staining and were processed and analyzed using NIS-elements advanced research software (Nikon Instrument Inc) and FIJI-Image J open software.

Cell Ranger h5 files were read into Seurat v4 98 (link) in R (version 4.1.0) and RStudio (version 1.4.1717) and merged by brain region (DMH, SCN) for clustering analysis. We filtered the initial datasets to remove low quality samples (i.e., cells with less than 100 genes detected or greater than 0.5% mitochondrial reads). We then log-normalized the data; selected 2,000 most variable genes (“feature selection”), and scaled gene expression. We performed Principal Component Analysis (PCA) to linearly reduce the dimensionality of the highly variable gene set. We defined distance metrics based on K-nearest neighbor analysis, grouped cells with Louvian algorithm modality optimization, and visualized cell embeddings in low-dimensional space with Uniform Manifold Approximation and Projection (UMAP) nonlinear dimensionality reduction. To focus our analysis on neurons, we subsetted neuronal clusters based on their enriched expression of neuronal marker genes (Syt1, Syn1, Tubb3). To correct for batch effects, we integrated across sample batches using Seurat’s function for reciprocal principal component analysis (RPCA). Next, we subsetted region-specific clusters based on expression of positive and negative marker genes for each target brain region (SCN, DMH), as described in the next section. We reclustered the identified DMH and SCN neurons using the following parameters: DMH, 2,000 most variable genes, first 15 PCs, resolution setting of 0.8; SCN, 2,000 most variable genes, first 13 PCs, resolution setting of 0.5 Finally, we assessed cluster markers with the Wilcoxon Rank Sum test using Seurat default settings. Cluster markers were selected based on top p-values (adjusted to correct for multiple comparisons), high percent expression within the cluster and low percent expression outside of the cluster, and validated based on Allen Brain Atlas mouse in situ hybridization data and previous literature.
